Fig. 1: Principles and applications of hyperbolic metamaterials.
figure 1

Isofrequency contour for a isotropic, b anisotropic media, and c Type-I and d Type-II hyperbolic materials. Different hyperbolic material designs: e multilayer hyperbolic metamaterial (HMM), f nanowire HMM, g hyperbolic metasurface, and h natural hyperbolic material. Different applications of HMMs: i a HMM hyperlens, j negative refraction in a plasmonic grating HMS, and k spontaneous emission enhancement above a silver surface (top) and a HMM (bottom). i, j, and k are adapted from refs. 3,13, and 16, respectively
